Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If three-dimensional position information is stored without encryption, then data management is simple, but data integrity and reliability cannot be ensured
Solution Approach 1:
The patent applies preliminary action by encrypting the three-dimensional position information before storage. The encryption process includes generating ciphertext from the position information using cryptographic algorithms, and storing both the ciphertext and corresponding verification information (hash values, digital signatures) in advance. This preliminary encryption ensures data integrity and reliability from the moment of storage, preventing unauthorized modification while maintaining a structured management system through verified storage protocols.
2Adaptability or versatility
If measurement data is collected from multiple industries without uniform accuracy criteria, then data coverage is comprehensive, but data quality and accuracy cannot be unified
Solution Approach 1:
The patent applies parameter changes by transforming the position information into a standardized cryptographic format regardless of its original measurement accuracy. The system encrypts position information from various industries using uniform cryptographic parameters (encryption algorithms, key management, verification methods), converting diverse data sources into a consistent verified format. This allows comprehensive data coverage from multiple industries while ensuring uniform data quality through standardized encryption and verification parameters.
3Reliability
If verification information is stored with position information, then falsification can be detected, but storage space requirements increase
Solution Approach 1:
The patent applies the taking out principle by extracting and separately storing verification information (such as hash values and digital signature data) from the original position information. Instead of duplicating the entire position data set for verification purposes, the system extracts critical verification elements and stores them in a separate verification information storage unit. This significantly reduces storage space requirements while maintaining comprehensive falsification detection capability, as the extracted verification data is much smaller than the original position information.

AI summary
A three-dimensional position information generation unit (210) generates three-dimensional position information using measured data acquired by a measurement instrument (201). An additional information acquisition unit (220) acquires, as additional information, at least any one of authenticated user information, instrument information, and measurement information. An information encryption unit (231) encrypts a set of the generated three-dimensional position information and the acquired additional information.
